ELECTRICAL DRY SHAVING IMPLEMENT HAV- ING A HINGEABLE SHEARING SECTION Jacob L. Kleinman, New York, N.Y." Application April 21, 195s, serial No. 729,928 4 Ciaims. (Ci. `.9o- 43) This invention relates to the construction of shaving implementsl in general, and more particularly to atype operated by. a motor and known as dry shavers or electric razors.

The present type of electric shavers are constructed in` such a manner wherein only one of the outer side por tions of the motor shaft is connectedto the actuating elements for operable purposes; this form of structure prevents even-distribution of the motor-power upon the motor shaft and causes eccentric strain upon such motor shaft thereby burdening the motor with excessive strain while operatingK the actuating elements for shavingfpurposes. Thus the present type of shaver must be provided with an eXtra-powerful motor of a size and structure larger than actually needed for an instrument of this kind.

Furthermore; such eccentric strain causes additional frictional rubbing of the outer shaft portion withinits seat, constantly removing material therefrom, to an eX- of the motor shaft, I provided such end portions with engagementmeans located at varying degrees, thus preventing locking (of movements) ofthe parts during operation. y

it will thus be seen that an object of thepresent'invention is the provision ofpa shaving implementhaving a motor secured to a'receptacle in a-stationary non-mova-v VVest possible commercial use.

Vselected for illustration of my novel construction, a shav- Patented May lO, 1960 `viding gripping means for the users hand while shaving.

It is a further object of this invention to provide an electric shaver comprising an improved mechanism disposed in a housing which can be easily held in thefhand in a convenient rmanner for shaving purposes.

' A still further object of this yinvention isl the provision of a new and improved electrically operated shaving implement wherein the component parts can be readily assembled, and whereinthev shaver is of sturdy and foolproof construction having a trouble-free life manyf times that of similarimplementsavailable, and whichis relatively inexpensive to manufacture.

The variety of possible application of my novel construction in connection with different types of shaving implements, as hereinabove indicated, is so proliiic'that for the'purpose ofillustrating the invention the specific embodiment of my invention in its application to a shaving implement exhibitingthe greatest difliculties has been selected, Such shaving implement is one which necessarily mustV conform most rigidly to the contours of the portion to be shaved and one which has the field of great- For this purpose I have ing implement constituting -a multiple-head electrically operated shaver, so that the principles of construction may be best illustrated in a shaving implement known as a multiple-head electric shaver. i

For a fuller understanding of the nature and ohiects of `the invention, reference is had to the following detailed tent whereby such shaft becomes too loosewithin its seat description in connection with the accompanying drawings, in which:

The under-face of the receptacle 11 is provided with two spaced apart downwardly extending wall portions 14 for having the upper portion of the motor N placed therebetween and secured thereto by suitable means, for example, rivets or screw-elements 15, in a manner preventing lateral movements therebetween (see Fig. 2).

A shaft 7 (Fig. 17) is provided at one of its end portions with a disk R' secured thereto in a non-movable manner; for example, the end portion of such shaft 7' Aisv shaped to provide a flat portion 28 adapted to be positioned Ytightly within they opening 29 of Vthe disk R (Fig. 18), or bevsecured thereto by means 'of solder, or such flat portion may be riveted over or spread within the opening 29 for example as shown at R". A washer 24 having a flanged portion 25 is then placed loosely over such shaft 7' and positioned against the inner face of the cutter for frictiorial engagement therewith to effect a'v shearing action therebetween for shaving purposes,

v I am `showing the figures herein for illustrativepurposes, for a better understanding of my invention, to be disk R'. A circular-shaped element 26 having an eccentric opening is then placed over the shaft 7 and positioned at about the center portion of such shaft 7 and secured thereto by suitable means; for example, frictioniit; or such element 26 may be an integral portion of the shaft 7;`the object of this element 26 is to provide the shaft 7' with aV centrally located eccentric portion 26 for a purpose which will be hereinafter explained.

This shaft 7 is then placed through an opening 17 in one of the wall portions 16 carrying the eccentric portion 26' into the receptacle 1l; the washer 24 is then placed frictionally into such opening 17 having its flange portion 25 'overlying and covering the joint therebetween. A second washer, 27, similar in structure to the washer 24, is then placed into the opening of the opposite wall portion 16; the fiat-shaped section 23 ofthe end portion 30 is then placed loosely through the opening of such washer 27 and then in a frictional manner into the opening 29. of the disk L and secured thereto in the same manner as indicated by the numeral R".

The disks R and R are each provided with suitable fastening means for example pins P and P adapted to be positioned through openings 35 and 35"located at the end portions of the bar-element C for holding such disks R andR in acertain parallel position with respect to each other, for example, in a manneras shown in Fig.

able to properly describe the herein invention, and not for limitation purposes.A Y

Referring more particularly to the drawing, in which similar reference characters identify similar parts in the several views," in my novel shaving implement.

Arrow A indicates the handle structure of my shaving implement `and arrow B indicates my assembled shearing section of my shaving implement. f

Numeral 5 indicates the handle-casing for housing therein the motorN, and arrow E indicates the hingeable carrier forming an assembled removable Yor hingeable shearing section carrying the individual shaving units d and the actuating structure 4 (Fig. 1). v f

The'mot'or N is provided with a shaft 7' having the end e portions thereof extending outwardly of such motor; one

- left-hand-disk L (Figs. 2, i-and 4) for a purpose which will be hereinafter explained. Y

3. The disks L and L' are yeach likewise provided with similar fastening means for example such as pins P1 and P2 for holding the bar-element D secured thereto.

It should be noted, that while the pins Vl and` P and the bridgeable' .bar.element C :are located in a certain position, the pins P1 and vP2 land the bridgeable bar element D are located in a varying or different position, that is, at a different degree; for example as shown in Fig. 4 (also see Fig. 2). Thus, while the motor shaft 7 is being rotated neither one of the bar-elements, C or D, will lock and cease to operate; instead, each one of the bar-elements will rotate itsupper disk and cause the upper ldisk on the other end portion of the shaft 7 to move the other of the bar elements out of locking position thereby assuring continuous operation of the implement while shaving.

This type of structure is a very important feature of my herein invention. For clarification purposes I desire to point -out the following: `In the present type of electrically operated shavers only one end portion. of the rotatable motor shaft is employed to operate the actuating structure for operating the shaving units for shaving purpose; this form of structure places an eccentric strain upon such motor-shaft during operation, it prevents proper precisionalrotatable movements of such shaft Within its seat, it burdens the motor with-excessive strain thereby shortening the life of such motor.

It is thus evident that my present invention, wherein both end portions of the motor shaft are connected to two end portions of an upper shaft for having a portion thereof operate, centrally, an actuating structure, is a desirable contribution to the art of making electrically operated shaving implements; it reduces motor-strain to a minimum thereby prolonging the life of the instrument and greatly improving the service thereof.

The carrier indicated by arrow E comprises a base portion 41 having two bifurcated or slitted sections 42 and 43. These sections are each shaped to provide spaced projections or ridges 46 and 47 separated by grooved sections 44 and 45. This carrier E is also provided with wall portions 4d and 49 and with a through opening 50 and also with two inwardly projecting floor portions 51 and 52 each terminating into a downwardly projecting extension 53 and 54 having openings 55. The wall portion 48 is provided with a rib section 56 having hook-portions 57; and the wall portion 49 is provided with a rearextending section 53 having slitted pins 59 and 59' each having a shoulder portion 59" fora purpose which will be hereinafter explained (Figs. 1 and 6).

The individual shaving units d are each provided with undercut hook portions d1 and d2. These units'are placed upon the sections 42 and 43 (Figs. 6, 20 and 30) having their neck portions d3 and d4 positioned adjacent the grooved sections 44 and 45 land being moved thereinto in a manner whereby while the baseportion or under-face d5, of each shaving unit d, engages the upper face 4tiof the sections 42 and 43, the hook portions d1 and d2 will engage frictionally the under-faces of the ridges 46 and'47 (Fig. 30) and hold its respectiveshaving unit secured in desired position. I

'Ihe actuating structure 4 comprises a bifurcated or slotted base portion F (Fig. 7) having a neck portion F' which is provided with an opening F".w The neck portion F' is provided with a bridge section F1 having stem portions F2 each provided with sidewardly-extending circular-shaped pins 3, for a purpose which will be hereinafter explained.

This actuating structure 4 is placed between the two downwardly projecting extensions 53 :and 54, in a manner whereby the opening F is located in proper alignment with the openings 55, having a pivot, pin or screw-element F3 vpositioned therethrough permitting pivotal movements of such actuating structure 4 in eitherdirections (Fig. 9). vIt may be noted that the floor portions '51 and 52 are eachofv such a size in width whereby the side portions thereof will engage and limit the side movements ofthe actuating structure 4, as shown by dotted lines' F4and F4 engaging the door portion 51, see numerals 51" and in desired position by the carrier E (Figs. 1, 8 and 9).

The slitted pins 59 and 59' are each provided with 'a circular-shaped spring member S positioned thereover. These spring members S are each provided with an vangularly disposed end portion S (positioned within the slots S of such slitted pins 59 and 59') and with a coiled or looped end portion S1 (Figs. l0 and l1).

The connection of the carrier E to the lreceptacle 11 is, in accordance with my invention, a very simple and easy operation; placing the shoulder portions 59 of the carrier E into position within the grooved end portions 21 of the receptacle 11 will place the slitted pins 59, including thespring members S, into the spacious hollow section 21 (Fig. l0); this will place the'coiled end portions VS1 into position to. be hookedonto the shoulder portions S2 and be held safely thereon by the head lsections S3.

When the carrier E is placed upon the receptacleV 11 i-t will be found that the coiled end portion S1 is located in a position remote from the shoulder portionV S2 of :the receptacle 11 (Fig. 5), `for example'as indicated. by

the dotted lines S4 (Fig. l11); bringing such end portion S1 into position and connecting same to the shoulder portion S2 will cause such spring member S to provide spring tension and urge the angularly disposed end portion S to move the carrier E (carrying the shaving units d and the actuating structure 4) into a hinged-open nonshaving position, disconnecting such actuating structure 4 from the shaft 7', for example, as shown in Fig. 1.

Placing the carrier E back into normal shaving position will cause the hook portions 57 to enter the openings 62,

'of the wall portion W, and become interlocked, underneath such wall portion W, by having the slidable elements 6,3 placed into the grooved sections 64 and engage frictionally such 4hook portionsv 57 (Figs. 1, 5 and 13). Thus such carrier E may be held in desired position'for shaving purposes. 1

My above-mentioned slidable elements 63 may be constructed in any suitable manner; but for illustrative purposes I am showing such slidable structure comprising a ibase portion 65 carrying angularly disposed elements 63 (Figs. 13, 14 and 15). The wall portion 61 of the handle casing 5 is provided with an opening or slot 61 of suitable shape and size. The slidable locking gauge indicated by arrow V (Fig. l and 14) comprises an element 66 positioned within the slot 61'; this element 66 is 'of a size adapta-ble to slide within the slot 61', for

A51", thus such actuating structure 4 will always be held the purpose of carrying the base portion 65 (to which it is secured by suitable pins or screw-elements 67) to-V wards either direction sidewardly of the handle 5. For example; moving the outer section 66' of the element 66 towards the side end portion 5" will cause such element 66 to carry the base portion 65 towards each side portion 5" and move the slidable elements 63 out of the grooved sections 64 (away from the hook portions 57), thereby enabling the spring tension of the spring S to urge the ycarrier E into a hinged-open position as shown in Fig. f1; whereas, movingsuch outer section 66' towards the center portion of the handle, as indicated Ihy arrow 3a (after the carrier Erhas been moved back into normal shaving position), will cause the base portion 65 to carry the slidable elements 63 into the grooved sections 64,for engaging the'hook portions 57 to hold such carrier E in locked position for shaving purposes.

The outer section 66', of the element 66, is' of a size larger than that of the slot or opening 61'; for example, it is provided with extending ange portions 66 of a size and shape adapted to cover such slot 66' from view regardless of the location of the locking gauge V.

.To facilitate the locking operation, I have provided the hoolcvportions 57 with reduced or tapered end portions 57a, serving as guiding means to'facilitate the entering movement; of the slidable elements 63 into the grooved sections 64.

The under-face d5 of the shaving unit d (Fig. 20) is provided with a centrally loca-ted opening d6, for having one of the stern portions F2 positioned therein to engage `the inner movable shearing member d8; to operate same for shaving purposes.

4My shaving unit illustrated in Figs. 21-29 and 3l is constructed upon an entirely new principle; this structure is practical, useful and economical to be manufactured. This unit comprises an outer stationary shear-member M and' an inner movable shear-member M' (Fig. 29).

The stationary shear-member M comprises a thin metallic sheet-portion M1, perforated centrally thereof, having two of its side portions secured to elements M2 (Fig. 22).`

4is positioned upon one of theelements M2, having the flange section M3 turn or bend over such end portion M2' as shown at M3 andclamped thereto. If desired, solder, welding-process or other means may be utilized to secure such end portion M to its seat. The same process is employed with respect to the second or'opposite end' portion M andthe other element M2 (Figs. 22-24).

The sheet portion M1 is then bent into desired shape and the end portions M14 of the elements M2 are then shaped into desired form partly inclined as at M4' (see Figs. 25 and 31) and connected to each other by suitable means in any desirable manner; for example, as shown at M wherein the end portions M4 are connected to each other by spot-welding process, thus completing the construction of my new stationary shear member M.

The inner movable shear member M comprises two spaced apart wall portions 1a each having an inwardlylocated wall-section 1b. The wall portions 1a are connected to each other by a perforated bridge-section 1a1. The front lwall portions 1b are each provided with a grooved or slitted section 1a, and the rear end portions 1b" are each provided with a grooved or slitted section 1a" of a size double the length of that of the grooved sections 1a'. These wall portions 1b are each provided with a centrally located slot 1d and with inclined edge portions 1d and 1d for a purpose which Will be hereinafter explained (Fig. 21.)

A spring plate 71, having at one of its end por-tion a vpair of at ilange sections 72, is at the other of its end portion provided with a semi-circular-shaped section 73. This spring plate 71 is secured to the inner movable shear member M' in the following manner. The ilange sections 72 are placed into the slots 1a and moved for*- ward to an extent whereby'the section 73 is located in front of the grooved sections la (Fig. 27); the ange portions 73 are then placed into the slots 1a and moved thereinto to an extent whereby the ange sections 72 will be located within the slots 1a" adjacent to the outer end portions thereof (Fig. 28); the semi-circular end portions 73 will t tightly within the slots'la' and thus hold the at-spring 71 secured in its position (Fig. 29).

Such assembled inner movable shear member M' is placed into the stationary shear member M before the end portions M4 are connected to each other thus Ithe stationary shear member and the inner movable shear member form an assembled shaving unit.

It should be noted that the center portion of the spring plate 71 fits loosely between the two wall portions 1b, and that the two flange sections 72 tit loosely within the grooved sections or slots la" for a purpose which will be hereinafter explained.

The sections 2 (Figs. 22 and 23) when connected to each other as shown in Fig. 31 form a neck portion d3' similar to the neck portion d3 as shown in Fig. 20, and the end portions M4 form hook portions d3 similar to the hook portions d1 as shown in such Fig. 20. 'Ihese hook portions d1 may be secured Ito the ridges 46 of the carrier E in the same manner as are the hook portions dl; as clearly shown in Fig. 31. For clarification purposes I am showing space between the connecting portions; whereas, in reality, such connections are made in a frictional manner.

The thickness of the individual stem portion F2 is of such a size adapted to tit loosely between the two wall portions 1b, and the pins 3 are of a size adapted to tit loosely within the grooved section or slot 1d; so that and be removed therefrom as an assembled unit.

when the assembled shear unit indicated by arrow K l (Fig. 29) is placed in shaving position upon the carrier E, the pin portions 3 will slide upon the slanted edge portions ld' or 1d", of the wall por-tions 1b, until such pins 3 will slide into the slots 1d in which case the upper portion 3a of the stem F2 will press against the center portion of the Hat-spring 71, causingV the flange sections 72to move within the solts 1a to an Vextent permitting such spring 71 to Hex (as indicated by the dotted lines 3b) and provide spring-tension for urging the perforated bridge section 1a1, of the movable shear member M', into frictional engagement with the perforated sheet portion M1 of stationary shear member M for shaving purposes.

The pins 3 may be made in a manner as shown in Fig. 7, wherein such pins 3 are located below the upper portion 3a; but, it desired, such pins 3 may be located on top of the stem portion F2, for example, as shown in Fig. 8. The disclosures herein are for illustrative purposes only and not for limitation purposes.

lf desired, the portion 73 of the spring 71 may be shaped in a flat manner, and the slot 1a' may be of a size wherein such portion 73 may be positioned therein in a frictional manner and thus be held secured in desired position. Or other means, for example welding-process, may be utilized for holding such flat-spring 71 in desired operable position for shaving purposes.

The operable action for moving the inner movable shear member M is concentrated upon the pin portions 3 located within the slots 1d of such movable shear member, but there is no strain upon the spring 71 for displacing same from its position within the slots 1a' or 1a".

If desired, the structure of the inner movable shear member may be modied; for example, to an extent as shown in Fig. 32. Wherein the inner movable shear member' indicated by arrow I, comprises a perforated fiatshaped metallic clement 81 having flange portions 82 located at a lower level than that of the upper face of the metallic element 81. A yieldable structure 83, comprising ange portions 84 having angularly disposed Wall portions 85 shaped to provide slanting wall portions 86, terminating into a centrally located recessed or semicircular shaped portion S7, is secured to the metallic element 81 by any suitable means; for example, welding process or rivets 88 uniting or connecting the ange portion S2 with the flange portions S4. This structure may be positioned within the stationary shear member M forming a completed shaving unit.

In this form of structure the pin portions 3 of the actuating structure 4 may be eliminated. The top portions 3a may be positioned within the recessed portion 87, and press the yieldable structure towards the element 81, urging such element 81 towards frictional engagement with the shearing face of the shear member M; and simultaneously therewith move such movable shear mem- .ber towards either one of the end portions of the stationary shear member M, as indicated bythe dotted lines 3d, (Fig. 29) for shaving purposes.

From the above it is clear that the motor N and the receptacle 11 and the carrier E including the shaving units dand the actuating structure 4 areall united into an assembled unitary structure. This unitary structure can be placed into the handle casing 5 as an assembled unit For example; the handle casing 5 is provided with a rear Wall portion 61 and with side wall portions 91 and with a oor portion 92 (Fig. 15). The side wall portions 91 are each provided with an inwardly disposed channel or grooved section 93 of a size adapted to hold therein the side portions 18 and 19 of the receptacle 11, as shown at numeral Figs. 3 and 4.

The receptacle 11 is of a size shorter (or smaller) than the size between the wall por-tions 18 and 19, and is held in a non-movable position within the handle 5 by the inwardly disposed extending portions 94.

The channel portions 93 are each of such a size whereby the slitted pins 59 and 59 and the spring members S and also the head sections S3 may be housed therein when the wall portions 18 and 19 are located therein.

This assembled unitary structure may be placed within the handle 5 by sliding the wall portions 18 and 19 into their respective channel section 93 of such handle 5, and may be removed therefrom by sliding such wall portions 18 and 19 outwardly of such channel sections 93.

My handle casing` 5 may be constructed in any suitable manner. For example, formed of two sections, or provided with a cover, or in a cup-shaped style. For illustrative purposes I am showing my handle casing provided .for starting the motor N for operable purposes. Removing the cable-cord 95 from the pins 95 will stop the operation of the motor N (Fig. 1).

The upper wall portions 96 are each provided with an outwardly lined or slantingly disposed inner face 96', that is, the upper portions of each of the faces 96' (which face each other) are spaced further apart than are the lower portionsthereof (Figs. 3 and 4). The shaving units d are each shaped in a manner whereby their inclined or obliqued end portion 97 will t closely to such outwardly lined faces 96', thus forming or providing a close connection between the shaving units and their respective facing wall portions 96'; preventing the escape of sheared-,hair and minimizing rattling of the shearing unitswhile shaving.

If desired, 'the three individual shaving units d may be arranged in a manner whereby the shearing face of the center unit df may be situated at a lower level than that of the side units df' and df (Fig. 33), thereby providing an Y enlarged shearing area for shaving purposes.

` The present type of electric shavers are s`o constructed that they frequently slip out of the users hand while shaving, causing damage thereto. To prevent such occurrences, I provided my shaving implement with a suitably located recessed or depressed portion 99, for example, at the side portions thereof (see Figs. l, 3, 4 and l5), of a shape whereby the user may engage such depressed prtion with his lingers and hold such Vimplement safely in `his hand, thus minimizing the possibilities of the shaving implement slipping out of the users hand, preserving the precisionally-built mechanical structure of such shaving implements and the intactness thereof, thereby prolonging the life and usefulness of the shaving implement.

From the above it is evident that my present invention teaches an entirely new form of Vstructure in the art of making electrically operated shaving implements. The novel form, or manner, in which my shaving implement is constructed; the novel feature of having my receptacle carrying the motor and simultaneously therewith carrying the removable (or hingeable) shearing section and also carrying the mechanism for operating such shearing section, and wherein such shearing section is carrying the shaving units and is also carrying the actuating structure for operating such shaving units; this novel form of structure wherein the receptacle is carrying the entire mechanisrmand in addition thereto, such receptacle is also provided with means whereby the entire assembled unitary structure may be positioned into the handle casing in a slidable manner as an assembled unit and be held therein without the aid of screwelements, and may be removed from such handle casing as an assembled unit,

ing implements. This form of structure presents improvements eliminating eccentric strain of the mot0rshaft thereby minimizing strained frictional engagement, or rubbing, of motor parts; thus prolonging the usefulness of such parts and increase the life, or duration of usefulness, of such shaving implement. And also the fact that my shaving units are of a simplified form of structure, will greatly reduce the manufacturing cost of my units and thus of my shaving implement.

It will therefore be seen, that I haveinvented and perfected a shaving implement provided with an operable mechanism of a new and unique design and structure, a shaving implement which is practical and useful, economical to be manufactured and therefore of commercial value, and although I have shown certain preferred forms or illustrations in order to describe and explain the novelty of my invention, yet, by showing such structures, I

do not, by any means, limit myself to these structures, nor to the terms used in describing same, as they are for illustrative purposes only. Various suggestions and changes of structure may be resorted to, and I desire it to be understood that I have same in mind when showing and describing this invention, and seek protection by Letters Patent. And although I have mentioned in describing this invention of what material certain -parts may be made, how they may be formed, shaped or styled,- and how they may be assembled, yet, I desire it to be understood, that this structure, or parts thereof, may be made of any suitable material; shaped,'formed, styledA or arranged in any suitable manner, and assembledin any suitable or convenient way, so that the parts maybe easily taken apart, removed, cleaned, replaced and/orfreassem, bled, and that various changes in detail may be resorted to without departing from the spirit of this invention.

I claim:
